signumAdjacencyFunction: Hard-thresholding adjacency function
Description
This function transforms correlations or other measures of similarity into an unweighted network
adjacency.
Usage
signumAdjacencyFunction(corMat, threshold)
Arguments
corMat
a matrix of correlations or other measures of similarity.
threshold
threshold for connecting nodes: all nodes whose corMat is above the threshold
will be connected in the resulting network.
Value
An unweighted adjacency matrix of the same dimensions as the input corMat.
